CONTROLLER REGULATOR FOR CHARGING BOILER ST-24 TECH

The ST-24 Sigma microprocessor controller is designed to control the charging central heating boiler equipped with blowing and CH water circulation pump. Its task is to maintain the set temperature using a fan. The controller housing is adapted for installation on the boiler.

Functions performed by the controller:

• Fan control
• CH pump control
• slower fan operation when approaching the set temperature

Controller equipment:

• LED display
• CO temperature sensor
• temperature protection (thermal)
• housing designed for installation on the boiler
